Environment variable set in batch file cannot be accessed in the C code compiled by the file

Question

I'm setting a var using set TEST_VAR=5 and then I'm compiling a C code. Error found during compilation is TEST_VAR is an undeclared variable.

Answer 1

Wild-assed guess, because you don't even show a single line of C code: getenv(TEST_VAR) should be getenv("TEST_VAR").
